[SOLVED] Linux 3.17 broke Lenovo T520 wifi
Hi. I have a Lenovo T520 laptop, and the 3.17 kernel broke my
wifi.
I keep getting disconnected from the router without even ever
being able to look up addresses.
Not sure what output would help, but below are some of the
journalctl output.
One strange thing is this line:
Nov 16 13:10:18 simendsjo-t520 kernel: cfg80211: Calling CRDA for country: GBI'm in Norway. I tried calling
# iw reg set NObut this doesn't seem to do anything at all.
Any idea what might be wrong?
Let me know if additional output is necessary.

Re: [SOLVED] Linux 3.17 broke Lenovo T520 wifi
Have you downgraded the kernel, to make sure it's the kernel that has broken it and not another package?
Claire is fine.
Problems? I have dysgraphia, so clear and concise please.

Yes, I'm running 3.16 to get it working.
Tested two versions too:
linux-3.17.2
linux-ck-3.17.3

Re: [SOLVED] Linux 3.17 broke Lenovo T520 wifi
I can't know for sure... but I also have an iwlwifi driven wireless card and all of the sudden can't connect to my home router (WPA2). I can connect to my home network with my phone, and connect to my phone via wirless tether with my computer. But computer to home network is a no-go.
@simendsjo Unfortunately, trying both 3.17-1 and 3.16-4 didn't solve my issue. Did you downgrade anything else, or could you post the output of your network-related packages and how you're connecting? I'm using wicd (tried both curses and gtk) and get the same (Reason: 3=DEAUTH_LEAVING) in dmesg. Per this possibly related thread, I also just downgraded wpa_supplicant and iproute2 with no success.
Current relevant packages:
libutil-linux 2.25.2-1
linux 3.16.4-1
linux-api-headers 3.16.2-1
linux-firmware 20141009.0e5f637-1
util-linux 2.25.2-1
wicd 1.7.2.4-9
wpa_supplicant 2.2-2
dhcpcd 6.6.2-1
iproute2 3.15.0-1Happy to post with other output that would be helpful.

Re: [SOLVED] Linux 3.17 broke Lenovo T520 wifi
What says
$ lsmod |grep rtl8
$ lsmod |grep 80211I think the issue is related to the wifi card firmware.
If you have a rtl8723.., I already seen other users complaints.
What happen if you're using Win OS and drivers ?
do it good first, it will be faster than do it twice the saint

Re: [SOLVED] Linux 3.17 broke Lenovo T520 wifi
Hiho,
I had the same problem on my Thinkpad x240. Concerning the CRDA country code message, did you uncomment the NO entry in /etc/conf.d/wireless-regdom? As I had some further hardware trouble, I tried 3.18-rc4 kernel from linux-mainline, which made the kernel warning disappear. WLAN is stable now here.

I didn't even have crda or wireless-regdom installed. Installed them, fixed the config and booted, and now it works!
Thanks!

I only downgraded to linux-ck 3.16.2. I'm using netctl though. Did you see cycling_penguins answer? That worked for me at least.
